The massive cache of almost 400,000 Iraq war documents released by the WikiLeaks Web site revealed that small amounts of chemical weapons were found in Iraq and continued to surface for years after the 2003 US invasion, Wired magazine reported.

The documents showed that US troops continued to find chemical weapons and labs for years after the invasion, including remnants of Saddam Hussein’s chemical weapons arsenal — most of which had been destroyed following the Gulf War.

In August 2004, American troops were able to buy containers from locals of what they thought was liquid sulfur mustard, a blister agent, the documents revealed. The chemicals were triple-sealed and taken to a secure site.

Also in 2004, troops discovered a chemical lab in a house in Fallujah during a battle with insurgents. A chemical cache was also found in the city.
